Wanxiang Group Corp. outlined its intentions in a court filing as it pushes for a competitive auction of Fisker’s remaining assets.

California-based Fisker, which had planned to build cars at the former General Motors plant in Delaware, filed for bankruptcy protection in November. The move culminated a long, downward spiral that began after Fisker received a $529 million loan commitment from the US Department of Energy.

Wanxiang indicated in earlier court documents that it wanted to resume production of Fisker’s problem-plagued first-generation car, Karma, in Finland and eventually shift production to a Michigan facility. That dealt a setback to hopes of Delaware officials that cars would be built at the former GM site, where Democratic Gov. Jack Markell and Vice-President Joe Biden, Delaware’s former senior US senator, announced with great fanfare in 2009 that Fisker would revive vehicle production.

But in Wednesday’s court filing, Wanxiang said it intends not only to resume Karma production, but to continue development and design of a second-generation line of Fisker vehicles. Once such vehicles are ready for mass production “in volumes that necessitate a separate manufacturing facility,” Wanxiang intends to manufacture them at the now-shuttered GM plant in Wilmington.

Markell, whose administration provided about $20 million in loans and grants to Fisker to build cars in Delaware, welcomed the news of Wanxiang’s intentions.

“The sole purpose of the state’s loan and grant was to provide a future for a sector of the Delaware economy hard hit by the recession, so we strongly support any path forward that could lead to that result,” Markell said in an emailed response for comment. “The statement by Wanxiang _ a company that employs thousands of Americans in dozens of manufacturing plants across the US – about utilizing the Delaware plant is a positive development.”

It remains unclear, however, whether Wanxiang, which recently bought the company that served as Fisker’s primary battery supplier following a separate bankruptcy case, will be able to take control of Fisker itself.

Federal officials suspended the loans after Fisker failed to meet several sales and production milestones for its $100,000 Karma luxury car. The Karma’s problems included vehicle fires and recalls, problems with battery packs, the bankruptcy of Fisker’s primary battery supplier, and inventory losses from Superstorm Sandy, which destroyed hundreds of vehicles at a port in New Jersey.
